On my Blur LTc I have the factory with the trail adjust, I think I have it set on the firm however that only works in the Trail setting (where it spends 90% of it's life) it's failed once and lost all settings but was fixed on warranty. Testament to the frame/VPP that it took me about 2 months to properly notice it had gone.

If you get it go for one of the retuners to get it set for you and the bike which will probably remover the need for the trail adjsut
